Homemade Mint Slice Biscuits

With fathers day coming up, I started thinking of all the traditional things we buy for my dad. Socks, surf magazine, chocolate, a bottle of Bundaberg rum and a packet of mint slice… or two.

And what seems to be making its own tradition now is every Sunday is ‘recreate an Arnotts biscuit bake day!‘ It was a no brainer that today would be the day I attempted to make (rather than buy!) my dad’s favourite biscuit – delicious mint slice.

1230026_10151845507760295_1021519936_nExpecting there to be many ingredients and steps, I was surprised to find out how easy they were! They are great fun, especially when you get covered in rich and smooth, melted dark chocolate, and let me tell you: people will be amazed! I even shocked myself as I took the first bite!! With the thick dark chocolate coating, a subtle peppermint essence icing and the crunch from the chocolate biscuit, its bound to make everyone happy, and they are even better than the real things!




100g butter, cut into cubes and softened

1/2 cup caster sugar

1 egg yolk

135g plain flour,Β sifted

20g cocoa powder, sifted

1239516_10151845507545295_1536127282_nPEPPERMINT ESSENCE

2 cups icing sugar, sifted

1/4 teaspoon peppermint essence *available in the baking section at the supermarket!

2 tablespoons milk


400 g dark chocolate, roughly chopped *I used Nestle Plaistowe Premium Dark

splash of vegetable oil *this adds shine to the chocolate

2. Add the flour and the cocoa powder and mix until well combined.

3. Divide the dough into two equal portions. Shape into a disc and wrap each in cling wrap. Refrigerate for an hour. This process firms up the butter (fat) and changes the way in which the cookies will spread.

4. Preheat the oven to 180 degrees Celsius and line two trays with baking paper.

5. Remove one portion of the dough from the fridge and roll it out between two sheets of baking paper until about 6mm thick. Using a round cookie cutter (rather small), cut out shapes and place on the baking tray. Continue this process with all remaining dough – including the other half in your fridge!

6. Bake for about 10 minutes and remove from the oven. Allow to cool on trays for 5 minutes before moving them to a wire rack.

8. Once the cookies are cooled, spread the icing on to the top of each biscuit and allow it to set. Put a good dollop in the middle and push it to the edges with a knife, just like icing cupcakes. You don’t need to cover the entire top of the biscuit – as you can see in my picture. Make sure the icing has set before completing the next stage!

9. Make the chocolate coating – Combine the chopped chocolate and about 1/4 cup vegetable oil in a medium microwavable bowl. Heat for 30 seconds, remove stir, and heat for another 30 seconds. Repeat this process until most of the chocolate has melted. Continue stirring the last few chunks of chocolate as the residual heat will melt them. This ensures you don’t burn your chocolate!

Turn it over and submerge the entire biscuit in the chocolate. Allow for excess to drip off before you put them down on a tray with baking paper. Make sure you allow a good amount to drop off otherwise you will run out of chocolate and your biscuits will be very thick and heavy. You just want a nice coating, not one that makes it hard to eat!

11. Once all the cookies have been dipped and put on baking paper lined trays, you can put them in the fridge to set and keep cool! These are best kept in the fridge after to ensure they don’t melt and become soft!

I hope you all enjoy them!!! Especially my favourite girl Emily, over in Norway who can’t buy these! I hope you give them a try!!! Β πŸ™‚ xΒ 1236240_10151845507270295_1190158115_n

  1. Thank you so much for this recipe!!! I’ve had a major craving for mint slice biscuits but I’m living in the UK and fresh out of supplies. I just made these and they took me a while – anything more than a fried egg and I’m a bit of a dunce in the kitchen – but I finally just got to sample the fruits of my labour and they are even better than the real thing! I tweaked the recipe a bit and made my mint section more of a fondant icing, popped it in the fridge, rolled it out and cut it with a slightly smaller cookie cutter to fit the biscuit. These are amazeballs – I won’t be able to keep up with the demand on these! Thanks for the great recipe!!! I will definitely be trying a few other of your Arnotts biscuit recipes whenever I’m missing home πŸ™‚
